By choosing to participate in the Casper Test Net, you acknowledge that you have reviewed and will abide by the Test Net Code of Conduct and Incentive Requirements. Failure to do so may reduce or fully disqualify any Test Net incentive participation.
Before you set up your node, make sure it conforms to the minimum Recommended Hardware Specifications
Do not execute all the commands below as root.
sudois included where it is required.Expect that setting up a node and bonding it to the network will take about 30 minutes
Set a variable defining the version of the node package you're setting up. For 1.0.0, use 1_0_0
CASPER_VERSION=1_0_0
Set a variable defining the network name you're trying to set up. For example, for Main Net, use casper, while for Test Net use casper-test
CASPER_NETWORK=casper-test
sudo systemctl stop casper-node-launcher.service
sudo apt remove -y casper-client
sudo apt remove -y casper-node-launcher
sudo rm /etc/casper/casper-node-launcher-state.toml
sudo rm -rf /etc/casper/1_0_*
sudo rm -rf /var/lib/casper/*
Execute the following in order to add the Casper repository to apt in Ubuntu.
echo "deb https://repo.casperlabs.io/releases" bionic main | sudo tee -a /etc/apt/sources.list.d/casper.list
curl -O https://repo.casperlabs.io/casper-repo-pubkey.asc
sudo apt-key add casper-repo-pubkey.asc
sudo apt updatesudo apt install casper-node-launcher -y
sudo apt install casper-client -y
sudo -u casper /etc/casper/pull_casper_node_version.sh $CASPER_NETWORK.conf $CASPER_VERSION
sudo -u casper /etc/casper/config_from_example.sh $CASPER_VERSION
Let's get a known validator IP first. We'll use it multiple times later in the process.
KNOWN_ADDRESSES=$(sudo -u casper cat /etc/casper/$CASPER_VERSION/config.toml | grep known_addresses)
KNOWN_VALIDATOR_IPS=$(grep -oE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' <<< "$KNOWN_ADDRESSES")
IFS=' ' read -r KNOWN_VALIDATOR_IP _REST <<< "$KNOWN_VALIDATOR_IPS"
echo $KNOWN_VALIDATOR_IP
After running the commands above the $KNOWN_VALIDATOR_IP variable will contain IP address of a known validator.
Setting the
trusted_hashis only required if you join the network after Genesis has taken place. If you are joining prior to Genesis, you may skip this step and continue at "Start the node".
Get the trusted hash from the network:
# Get trusted_hash into config.toml
TRUSTED_HASH=$(casper-client get-block --node-address http://$KNOWN_VALIDATOR_IP:7777 -b 20 | jq -r .result.block.hash | tr -d '\n')
if [ "$TRUSTED_HASH" != "null" ]; then sudo -u casper sed -i "/trusted_hash =/c\trusted_hash = '$TRUSTED_HASH'" /etc/casper/$CASPER_VERSION/config.toml; fi
sudo logrotate -f /etc/logrotate.d/casper-node
sudo systemctl start casper-node-launcher; sleep 2
systemctl status casper-node-launcher
sudo tail -fn100 /var/log/casper/casper-node.log /var/log/casper/casper-node.stderr.log
curl -s http://$KNOWN_VALIDATOR_IP:8888/status | jq .peers
You should see your IP address on the list
curl -s http://127.0.0.1:8888/status
Before you do anything, such as trying to bond as a validator or perform any RPC calls, make sure your node has fully caught up with the network. You can recognize this by log entries that tell you that joining has finished, and that the RPC and REST servers have started:
{"timestamp":"Feb 09 02:28:35.577","level":"INFO","fields":{"message":"finished joining"},"target":"casper_node::cli"}
{"timestamp":"Feb 09 02:28:35.578","level":"INFO","fields":{"message":"started JSON-RPC server","address":"0.0.0.0:7777"},"target":"casper_node::components::rpc_server::http_server"}
{"timestamp":"Feb 09 02:28:35.578","level":"INFO","fields":{"message":"started REST server","address":"0.0.0.0:8888"},"target":"casper_node::components::rest_server::http_server"}
The following pre-requisite was not required during the Delta network but is highly advised during Test Net and Main Net
cd ~
BRANCH="1.0.20" \
&& git clone --branch ${BRANCH} https://github.com/WebAssembly/wabt.git "wabt-${BRANCH}" \
&& cd "wabt-${BRANCH}" \
&& git submodule update --init \
&& cd - \
&& cmake -S "wabt-${BRANCH}" -B "wabt-${BRANCH}/build" \
&& cmake --build "wabt-${BRANCH}/build" --parallel 8 \
&& sudo cmake --install "wabt-${BRANCH}/build" --prefix /usr --strip -v \
&& rm -rf "wabt-${BRANCH}"
If you don't have it yet, clone casper-node:
cd ~
git clone https://github.com/CasperLabs/casper-node.git
cd ~/casper-node
git fetch
Note
Verify that the version of your contracts matches the version of the casper-node software you have installed.
git checkout release-1.2
make clean
make setup-rs && make build-client-contracts -j
Go to Testnet CSPR.Live, and connect with the account you want to fund. Click Tools from the top navigation menu, then click Faucet. Wait for the faucet page to load, and click the Request tokens button. Wait until the request transaction succeeds.
Once you ensure that your node is running correctly and is visible by other proceed to bonding.
Check your balance to ensure you have funds to bond:
If you followed the installation steps from this document you can run the following script to check the balance:
PUBLIC_KEY_HEX=$(sudo -u casper cat /etc/casper/validator_keys/public_key_hex)
STATE_ROOT_HASH=$(casper-client get-state-root-hash --node-address http://127.0.0.1:7777 | jq -r '.result | .state_root_hash')
PURSE_UREF=$(sudo -u casper casper-client query-state --node-address http://127.0.0.1:7777 --key "$PUBLIC_KEY_HEX" --state-root-hash "$STATE_ROOT_HASH" | jq -r '.result | .stored_value | .Account | .main_purse')
casper-client get-balance --node-address http://127.0.0.1:7777 --purse-uref "$PURSE_UREF" --state-root-hash "$STATE_ROOT_HASH" | jq -r '.result | .balance_value'
If you followed the installation steps from this document you can run the following script to bond. It substitutes the public key hex value for you and sends recommended argument values:
PUBLIC_KEY_HEX=$(sudo -u casper cat /etc/casper/validator_keys/public_key_hex)
CHAIN_NAME=$(curl -s http://127.0.0.1:8888/status | jq -r '.chainspec_name')
sudo -u casper casper-client put-deploy \
--chain-name "$CHAIN_NAME" \
--node-address "http://127.0.0.1:7777/" \
--secret-key "/etc/casper/validator_keys/secret_key.pem" \
--session-path "$HOME/casper-node/target/wasm32-unknown-unknown/release/add_bid.wasm" \
--payment-amount 3000000000 \
--gas-price=1 \
--session-arg=public_key:"public_key='$PUBLIC_KEY_HEX'" \
--session-arg=amount:"u512='900000000000'" \
--session-arg=delegation_rate:"u8='10'"
amount- This is the amount that is being bid. If the bid wins, this will be the validator’s initial bond amount. Recommended bid in amount is 90% of your faucet balance. This is900 CSPRor900000000000 motesas an argument to theadd_bidcontract deploy.delegation_rate- The percentage of rewards that the validator retains from delegators that delegate their tokens to the node.
Remember the deploy_hash returned in the response to query its status later.
Sending a transaction to the network does not mean that the transaction processed successfully. It’s important to check to see that the contract executed properly:
casper-client get-deploy --node-address http://127.0.0.1:7777 <DEPLOY_HASH> | jq .result.execution_results
Replace <DEPLOY_HASH> with the deploy hash of the transaction you want to check.
To determine if the bid was accepted, execute the following command:
casper-client get-auction-info --node-address http://127.0.0.1:7777
The bid should appear among the returned bids. If the public key associated with a bid appears in the validator_weights structure for an era, then the account is bonded in that era.
